A L11 manager will see your team as 1*, likewise you see a L11 manager as having 9* Legends, but thats relative to your manager Level.
You can possibly obtain 7*/8*/9* players, for 7* you can buy a 6* scout player for 50T thats close to obtaining 7* and in a few days of training and matches he will get to 7*, to get 8*/9* players you will need to use either the personal trainer or use the power training method with green boosters, power training is more effective in token spending than personal trainer but it does take time to power train players.
